Suncourt Inc. does not provide electrical connection information. For your safety and protection follow all instructions and
adhere to applicable building and/or electrical codes.
IMPORTANT WARNING
Due to the power of a booster fan, adequate protective measures must be taken to avoid possible contact with the impeller
blades. In-Line Duct Fans™ are designed to boost only dry (ambient) heated or cooled airflow in duct conduits of forced air
systems with temperatures between 50°F and 140°F. Suncourt Inc. accepts no responsibility for use of this product in other
applications.
EXPOSURE TO AIRFLOW TEMPERATURES EXCEEDING 140°F WILL PERMANENTLY DESTROY THE ELECTRIC
MOTOR VOIDING THE WARRANTY
NEVER EXPOSE YOUR IN-LINE DUCT FAN™ TO
TEMPERATURES OVER 140°F (60°C)
ELECTRICAL CONNECTIONS AND WIRING
“WARNING - To Reduce The Risk Of Fire, Electrical Shock Or Injury To Persons, Observe The Following:“
Installation work and electrical wiring must be done by qualified person (s) in accordance with all applicable codes and
standards, including fire-rated construction.
Your In-Line Duct Fan™ must be connected to a 110/120 Volt AC, 60Hz fuse or circuit breaker protected power source only in a
manner approved by all applicable codes. Never connect your In-Line Duct Fan™ to a 240 Volt AC blower motor or other 240
Volt system.
The wiring installation must be of an approved type and terminate at a junction box (field supplied) at the In-Line Duct Fan™
and furnace.The electrical junction box should be attached using self-drilling sheet metal screws with a maximum length of 1".
Do not pre-drill the electrical box mounting holes. Consult your furnace wiring diagram to locate the furnace fan power supply
wires. To connect to a variable speed furnace fan, please consult a qualified installer.
The ground wire (GREEN) must be terminated at the furnace or other suitable ground. The power source must be protected by
a fuse or circuit breaker rated at a minimum of 15 amperes.
You may also supply power to your In-Line Duct Fan™ via a Suncourt DS100 DuctStat® Plug-In Thermostat™ or a standard
on/off switch.
Operating range is 50°F (10°C) to 140°F (60°C). Exposure to temperatures outside this range voids the warranty.
IMPORTANT NOTICE
Single Speed
The motor of your In-Line Duct Fan™ may have 1 White and 1 Black wire or 2 Black wires. If you have a motor with a White and
Black wire, connect the White motor wire to the White supply wire and the Black motor wire to the Black supply wire. If you have
a motor with 2 black wires, connect either of the Black wires to the White supply wire and the other Black wire to the Black
supply wire.
Two Speed
Make sure you connect the colored wire as shown below. Failure to connect correctly will destroy the motor. No warranty claim
for an incorrectly wired motor will be accepted by Suncourt.

GENERAL INSTALLATION NOTES
For maximum performance and minimum noise, the best location to install your In-Line Duct Fan™ is 6 - 10 feet from the
register you wish to boost air to. To prevent air leaks use a good quality duct tape to seal seams in the ductwork after installing
the In-Line Duct Fan™. By utilizing tapered reducers you may use larger diameter duct fans in smaller diameter ducts. Always
leave your In-Line Duct Fan™ accessible for maintenance, cleaning or repair.
VARIABLE SPEED CONTROL
The in-line duct fans can be speed controlled using the Suncourt VS100 solid state speed control. Follow the installation
instructions included with the VS100.
NEVER USE A RHEOSTAT TO CONTROL FAN SPEED.
INSTALLATION INSTRUCTIONS
MODEL: DB100
1.Locate the place in the duct where you wish to install the In-Line Duct Fan™.
2.Tape the enclosed template to the duct with the arrow pointing in the direction of the airflow. Cut out the required opening by
first drilling a pilot hole and cutting along the dashed line using a jig saw or tin snips.
3.Place the Inductor ® In-Line Duct Fan™ in the opening, making sure that the fan blade can turn freely. Align the arrow on the
unit in direction of airflow.
4a.Connect the spring through the middle hole provided in the base plate, stretch the spring and bend over the end for a snug
installation. You may complete the installation by covering the seams in the duct with a good quality duct tape.
4b.Secure the In-Line Duct Fan™ in position with the supplied #6 sheet metal screws using the provided holes in the base plate
of the unit.
MODELS: DB200, DB204
1.Locate the place in the duct where you wish to install the In-Line Duct Fan. Align arrow label on unit in
direction of airflow.
FLEXIBLE DUCT
2a. Simply cut the flexible duct and slide the In-Line Duct Fan in place by slipping the cut flexible duct ends over the
crimped ends on the In-Line Duct Fan, making sure the unit is well supported. Complete the installation by securing the In-Line
Duct Fan to the flexible duct with good quality duct tape or nylon cable ties.
METAL DUCT
2b. Remove a section of the existing ductwork and slide the In-Line Duct Fan in place by slipping the duct ends over the
crimped ends of the unit. Complete the installation by securing the In-Line Duct Fan to the metal duct with the supplied #6 sheet
metal screws spaced evenly around the circumference on each end of the unit.
